Sowing dates can be coordinated to produce a mix of varieties, all ready for harvest at once, at ideal size.

SEED SELECTION

You may want to start with a few straightforward varieties, or with a professionally premixed selection of microgreens, then diversify later on. Johnny's currently offers four premixed options:

• Mild Micro Mix, a balanced combination of mild brassicas, in organic and conventional seed options.
• Spicy Micro Mix, a complement of sharper-tasting varieties, in organic and conventional seed options.
• Rainbow Sprinkles Micro Mix, a make-a-splash recipe of chard and beets in a rainbow of stem, leaf, and midvein colors.
• Confetti Radish Micro Mix, an easy, fast, colorful formulation, in organic and conventional seed options.

Our mixes are precisely formulated to produce a range of colors, flavors, and textures with excellent loft and compatible growth rates.

Microgreens have a quick turnaround time, but there are differences in growth rate between different types and varieties. The majority of vegetable varieties grown as microgreens are ready for harvest in about 2 weeks, though the brassicas mustard and radish have a faster growth rate and therefore mature faster than beets, carrots, or chard. Herbs grown as microgreens tend to be comparatively slow-growing, maturing in 16–25 days. Depending upon types, varieties, and environmental conditions, a production cycle can be prolonged up to 4 weeks and beyond.

Use our Microgreens Comparison Chart to become more familiar with the fast-growing and slow-growing groups, along with other distinguishing features, and to help you choose varieties to grow concurrently. With practice, sowing times can be coordinated to produce a mix of varieties, all ready for harvest at once, at optimal size and flavor.

To approximate the seed quantities that you will need, you will need to consider seeding density, a relationship we cover in more detail below, under Sowing. Another part of forecasting how much seed you will need involves approximating the quantity of product that you need to harvest to meet your market demand. To help you compare seed quantities to sow versus potential yield during the planning phase, we created a tech sheet detailing the results of our Microgreens Yield Trial (Averages) for 29 Popular Varieties. With some trialing, good record-keeping, and repetition, a grower can become adept at estimating seed requirements versus project yield, timing production cycles, and forecasting ROI.

GROWING MICROGREENS INDOORS OR UNDER COVER: SUPPLIES & SPACE

Due to the fragile nature of the product, microgreens are most often grown indoors, in greenhouses or other protective structures. Adequate temperatures, ventilation, and light are important and require additional attention and resources. Before you construct your microgreen set-up, calculate how much space you have or will need, and gather together a few supplies — many of which you may already have on hand:

• Growing medium. We recommend a soilless mix as the best growing medium for microgreens because any potting mix that includes compost or soil can increase the risk of soilborne disease. For this reason, the best soil for microgreens is actually not soil at all. In addition to soilless mixes, other types of growing media, such as foam sheets or woven textiles, are also available on the market.
• Microgreen trays. Microgreens are often sown into standard 1020 flats or 20-row seed flats filled with a light, sterile, soilless mix to a depth of 1½–2".
• Tray covers. Options for covering the seeds after sowing include paper towels, vermiculite, domed lids, or white plastic trays.
• Heat mats. Available in a range of sizes and materials, with daisy-chaining, timer, and monitoring features, heat mats can help provide consistent root-zone temperatures.
• Grow lights. Supplemental light is essential at during off-season production at most latitudes and/or when growing indoors.

• Circulation fans.

  Adequate ventilation is essential for disease prevention.
• Hanging benches. Raised platforms, tables, or hanging benches help keep plants safe and provide for ergonomics.

With their short crop cycles and minimal to no fertility requirements, microgreens are an excellent crop for hydroponic culture. See Introduction to Hydroponic Growing to learn more about systems and equipment for this production method.
